cave plates and come into contact with the corn which is fed in longitudinally. This form of threshingmachine necessitates the corn being fed longitudinally; it is impossible to employ it for corn fed inbroadside on. Likewise, it is impossible to use it for other cereals, e. g. peas, lupins and the like,

because the branches of their stems do not admit of the threshing-machine being driven properly, as the stems and also the grain would be completely torn up. As is well known, threshing machines of this character are so constructed that on a rapidly rotating drum are arranged a number of beaters, extending along the entire breadth of said drum and coordinating with the firmly fastened slats or strips of the threshing basket and by which, ordinarily, the corn or other cereal with stalks to be threshed is fed in broadside. The disadvantage of these and similar constructions of machines is that in operation they operate efficiently only when the rain is fed inwith regularity. Uneven feeding of the stalks results in the grain, as well as the straw, being completely mangled and crushed and in that condition it is unfit for use. In addition to the above, in such cases, the power required is such as can, through the care lessness of the operator, soon cause very annoying disturbances of the mechanism. The above disadvantages are brought about entirely by the fact that the strips at a given moment operate along their whole length.

An attempt-has indeed been made heretofore to remove the above disadvantage by arranging on the surface of a metal cylinder a number of short beatersor teeth. A more efficient operation of the machine has thus Specification of Letters Patent.

been attained but there still remains one great annoyance which is that the firm at tachment of these heaters or teeth is attended with greatestdifliculty since they break off very easily and, moreover, the use of a metal cylinder adds relatively great expense.

The disadvantages above described of all the forms of construction of known threshing machines are avoided in the present invention by eliminating the use of a metal cylinder and arranging the wheels, or drum heads, on a common axle and connecting the peripheries of said wheels by a number of strips which form a plurality of beaters or teeth extending parallel to the axle, said beaters being connected to inoperative intermediate members. The form of construction of such strips can be carried out in widely different ways; among others, the strips may be arranged in the form of steps. Preferably, according to the purpose for which they are intended, these strips are arranged in the form of steps in such a manner that at a given moment and a given point only one short heater or tooth is operative.

The object of the invention will be clear from the foregoing description and the ac companying drawings, in which:

Figure 1 is a vertical section through a known threshing machine provided with my new threshing drum, Fig; 2 is aperspective view of the improved drum alone, showing one arrangement of the strips, and; Fig. 3 shows a modified arrangement of construction of the drum.

Referring to the drawing, 1 designates the frame of a threshing-machine comprising a concave plate 2 on which is firmly fixed a number of strips or slats 3. The table 4 is provided with a funnel-shaped inlet 5 through which the corn or other cereal to be threshed is introduced, preferably transversely, but when the threshing-machine is suitably constructed in a different manner the corn or the like may be fed in longitudinally.

The threshing-drum solely constituting the subject-matter of my invention comprises an axle 6 preferably carrying two wheels 7. On the wheels 7 which turn rapidly with the axle 6 are placedv the strips forming. the novel feature of this invention, the method of construction of which has already been ClGSCllbGCl above and which may be worked out in a variety of ways; for example, as

may be constructed in such a manner that step-like members are formed of metallic strips. These stepped members consist of the long piece or portion 9 which represents the beater proper, and cross pieces 10 which connect the long pieces, above mentioned, to-

These strips may be of various lengths but they must be shorter than the breadths of the drum 8.

The strips 9 are preferably staggered in such manner that there is always one strip in one longitudinal plane of the drum, as shown in Fig. 2 and particularly in the development of the drum shown in Fig. 3. These strips 9 may, however, be arranged otherwise; for example, step-shaped bodies may be formed from iron bars, such as are represented in Figs. 2 and 3. These step-like bodies consist of the longitudinal parts 9 forming the beating-strips proper, and the transverse parts 10 which connect the individual longitudinal parts in the form of steps. Here also the step-like bodies are preferably formed in such manner that there is only one beating-strip in any longitudinal plane of the drum. By means of a threshing drum constructed in this manner I attain that at any part of the drum the corn or other cereal is worked at any time only on a relatively Any irregularities in the feed of the corn consequently do not have the material disadvantages of known threshing-machines comprising slats because the material is able to escape more or less in consequence of the only partial contact with the threshing-drum or the strips. The step'like arrangement of the strips has, in addition, the special advan tage that non-uniformly fed material is automatically distributed, and consequently all shaking, such as has occurred heretofore when non-uniform feeding took place, is avoided and a uniform force is constantly required for drivin The threshing-machine works just as well when the corn or other cereal is fed in the longitudinal direction or in the transverse direction, and like wise it is of no importance whether the cereal has only straight straw or branched stems.

It is to be understood that the constructive arrangement of these short strips is not limited to the above-described illustrative embodiments; numerous other constructions may be thought of without departing from the scope of the invention. Particularly, instead of two wheels 7, a larger number of wheels may be arranged on the axle 6 and each of these wheels may constitute a carrier for a number of strips. Also, two wheels may be connected by strips, and the strips may constitute the carriers for the short beating-strips proper.

I claim 1. In a threshing machine, the combination of a drum comprising spaced circular heads, an axis common to said heads, strips connecting the peripheral portions of the heads and secured thereto, each strip consisting of a plurality of beaters arranged parallel with the axis, and inoperative intermediate members connecting said beaters.

2. In a threshing machine, the combination of a drum comprising spaced circular heads, an axis common to said heads, strips connecting the peripheral portions of the heads and secured thereto, each strip consisting of a plurality of beaters arranged parallel with the axis, and inoperative inter mediate members arranged transversely of the axis and connecting the heaters aforesaid.

3. In a threshing machine, the combination of a drum comprising spaced circular heads, an axis common to said heads, a plurality of strips carried by said heads and each strip consisting of portions extending from an intermediate point outwardly to the heads in the form of opposed steps, each step portion consisting of a number of beaters arranged along the axis aforesaid and of other portions arranged transversely of the axis, said last mentioned portions connecting said beaters.

4. In a threshing machine, the combination of a drum comprising spaced circular heads, an axis common to said heads, a plura lity of strips carried by said heads and each strip consisting of portions extending from an intermediate point outwardly to the heads in the form of opposed steps, each step portion consisting of a number of heaters arranged along the axis aforesaid and of other portions arranged transversely of the axis, said last mentioned portions connecting said boaters, said beaters being so arranged that in a determined plane passing through the axis of the drum only one of the same is operative at a given time.

In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
